The known mechanical keying devices for the operation of matrix composing and line-casting machines or the like must be accurately ad.- justed relative to the machine in order to actuate the keys easily and reliably. They must touch the keys but must not depress them in the neutral position. The mechanisms are rather bulky in size and weight. If they are to be removed from the machine for one of various reasons, such as repairs, cleaning of the machine, or to'permit temporary manual operation of the keyboard by the type setter, the removal of the heavy weights requires at least two men. The removal of the mechanisms also involves hazards because space requirements. and mobility do not and thesupports occupy space. Even if the mechanisms are provided with rollers, they wear the floor of the workroom, especially because the forth and back movement is always along the same path. After every removal and replacement the mechanism must be readjusted relative to the keyboard and this requires considerable time and outage of the costly machines. The elimination of a part of these disadvantages by the installation of a wear resistant track, such as rails or the like; leads to new difficulties on account of the nature of the floor covering and of space.

The object of the present invention is a special device for the mounting of operating mechanisms of the aforedescribed kind, which avoids all of the aforementioned disadvantages. In accordance with the invention the operating mechanism is fastened to a support located at one side of the keyboard so as to be rotatable around a vertical or a horizontal axis. The arrangement permits of a very simple and easy mounting and adjustment of the attachment. The support may be fixed to the floor to which also the machine is fixed, or both may be fixed to a common bed plate. If after the initial mounting and adjustment the operating mechanism is rotated or lifted relative to the keyboard it can again be accurately replaced with respect tothe latter by the use of indicating marks or the like.

The accompanying drawings illustrate several embodiments of the invention. In the drawings:

Figure 1 illustrates the operating mechanism mounted on a pedestal and supported over the keyboard,

(Cl. 199l8) Fig; 2 illustrates a modification of the support embodying the invention, while Fig. 3 illustrates still another modification of the invention.

Referring to Fig. 1, the operating mechanism A B C D is arranged above the keyboard 2! of a matrix or line-casting machine. The mechanism. shown in the drawings is controlled in a known manner by a control ribbon R which during operation period is transferred from a roll i to a roll 2. The combinations punchedinthe ribbon R are transferred by the detector carriage D which is provided with detector pins 3, which in turn are raised and lowered by a crank 4, the latter being driven by a cam 5 mounted on a shaft ii. The thus detected signal combinations are transmitted to rods 8, which, dependent upon the manner in which they are combined, actuate corresponding rods 1. Power is supplied by a motor M which maybe connected and disconnected by means of a crank 8, lever l2 and coupling elements 9 and ill.

As shown in Fig. 1, the operating mechanism A B C D is mounted on a base C. This base C is rotatably mounted on a plate E which in turn is rotatably fastened to a column or pedestal I6. A latch M on the plate E engages a notch in the base C, while a latch it engages a notch in base It. When in the engaged position these latches thus fasten the respective elements in fixed relation to: each other and to the column I6. It is of course possible to provide for latching of the respective elements in other positions besides those shown.

In the modification shown in Fig. 2 the vertical support for the mechanism consists of telescoping tubes l'l, 22 and 23 by means of which the operating mechanism, after having been turned 90 counter-clockwise may be lowered to thus permit the keyboard of the typesetting machine to be swung out of its operating position.

In the modification illustrated in Fig. 3 the pedestal which supports the operating mechanism A B C D comprises a lower part l8 and an upper part I9 which are connected by a hingebolt 20 or the like, topermit relative rotation about the axis mechanism is swung out of the way. The machine may then be operated by hand. All maintenance work, such as the frequently necessary cleaning can be done without difiiculties. With machines in which the keyboard may be swung out of the operating position, the latter is free to be moved after the operating mechanism, which in this case may be mounted on a telescoping pedestal, is sufiiciently lowered. The operation of the adjustable mounting is very simple and requires only one workman.

What I claim as new and desire to secure by Letters Patent is:

1. In combination with a keyboard of a typesetting machine or the like, a unitary self supporting keying attachment for said keyboard, comprising, an operating mechanism and a stationary support for the latter arranged for independent mounting to one side of said keyboard and in fixed relation thereto and rigidly connected to said operating mechanism for normally supporting the latter in an operative position relative to said keyboard, said support being provided with a movable joint to permit movement of said mechanism from said operative position to another position for providing access to said keyboard.

2. In combination with a keyboard of a typesetting machine or the like, a keying attachment for said keyboard, comprising, an operating mechanism and a stationary support for the latter arranged to one side of said keyboard and rigidly vfor said keyboard, comprising,

connected to said operating mechanism for normally supporting it in an operative position relative to said keyboard, said support being provided with a telescoping joint adapted topermit rotative and rectilinear movement of said mechanism from said operative position to another position for providing access to said keyboard.

3. In combination with a keyboard of a typesetting machine or the like, a keying attachment for said keyboard, comprising, an operating mechanism and a stationary support for the latter arranged to one side of said keyboard and rigidly connected to said operating mechanism for normally supporting it in an operative position relative to said keyboard, said support being provided with a two part articulated column, the lower part thereof having a pivot for the upper part thereof, said upper part being attached to said mechanism and arranged to permit its rotation about said pivot from its normally upright position to an inclined position.

4. In combination with a keyboard of a typesetting machine or the like, a keying attachment an operating mechanism and a stationary support for the latter arranged to one side of said keyboard and rigidly connected to said operating mechanism for normally supporting it in an operative position relative to said keyboard, said support beingprovided with a two part articulated column, the

lower part thereof having a pivot for the upper part thereof, said upper part being attached to said mechanism and arranged to permit its rotation about said pivot from its normally upright position to an inclined position, said lower part being further provided with a base having an abutment adapted to limit the rotation of said upper part and forming a support therefor in its inclined position.
